Great addon. Just went out and gave my supressors a workout with standard military ball ammo. US made M4 sound was reduced drastically(I didn't need earplugs) however the "crack" was still heard downrange. The point of impact changed slightly(Still stayed within 1MOA). It also starts to smoke on cold days a bit, which looks awesome if someone knew how to implement this into game(the more you shoot, the hotter the suppressor gets). Modern snipers practice with and without the suppressor so that a shooter knows the POI change and can adjust in combat before the shot is taken. Hope this helps!!
